A safety system for an elevator that includes at least one control unit, which control unit is operable in at least two different operating modes. The safety system has at least one electronic lock connected with the control unit, and is connectable, or connected, with at least one electronic key. The control unit is programmed, or programmable, in such that, in the presence of a connection between the electronic key and the electronic lock, it is only operable in one operating mode of a first subset of the operating modes and, in the absence of a connection between the electronic key and the electronic lock, it is only operable in one operating mode of a second subset of the operating modes. A maintenance mode is only available in the second subset of the operating modes. |
